NCAM

NCAM: A state-space stock assessment model for Northern cod

General

  • An integrated state-space population dynamics model
  • Integrated
    • Uses as much information as possible
  • State-space
    • Includes process and observation equations + error
    • Population processes are informed by observations from multiple sources
    • Process errors are necessary for realistic stochastic projections

Data inputs

  • Reported landings (1983-2018)
  • Catch-at-age information (1983-2018)
  • Reported landings by month (1983-2018)
  • Offshore research vessel (RV) survey indices (1983-2018)
  • Inshore sentinel (SN) gillnet survey indices (1995-2018)
  • Inshore acoustic biomass surveys and age composition data from Smith Sound (SS; 1995-2009)
  • Tagging data (1983-2018)

Biological inputs

  • RV survey data were used fit cohort-based models of:
    • Proportion mature at age
    • Beginning of year and mid-year stock weights at age
  • Baseline natural mortality (M) values

Partial catches

  • User sets lower and upper bounds on total catch weight
  • Bounds are used via a censored likelihood

Change in Q

  • A shift in Q was assumed for the offshore RV survey
  • A variable portion of the stock is assumed to occupy Smith Sound between 1995-2009
  • Q for the inshore sentinel survey was assumed to follow a random walk
    • Done to account for potential changes in migration patterns

Tagging data

  • Age of tagged fish estimated from length-at-release using a spatiotemporal Von Bertalanffy growth model
  • Applies adjustments for tagging mortality, tag loss and reporting rates
  • Reporting rates estimated by an external model using the high-reward tag data collected since 1997
  • The Baranov catch equation was applied to age-based tag survivors
  • Assumes that initial fishing mortality experienced by fish in each experiment are random deviations from the fishing mortality experienced by the whole stock

Assumptions

Assume the same selectivity curve as estimated by NCAM in the terminal year and apply catch multipliers

  • The following catch multipliers were applied: 0, 0.7, 0.85, 1, 1.15, and 1.3
  • This translates to 0, 9658, 11727, 13797, 15867, and 17936 t of catch in the projection years

Assume natural mortality converges on the long-term mean, excluding the M spike between 1991 - 1994

Assume mean recruitment from the last three years

Assume averages weights and proportions mature from the last three years
